IPTV M3U is an application to load playlists of live TV channels, films, TV shows and other multimedia content.
M3U files are usually text files containing URLs or server addresses where TV channels or other multimedia content can be accessed. These files can be easily modified and edited using a regular text editor.
M3U files are often found on the internet, both free and paid. It is important to ensure that the source of the M3U file is legal and reliable to avoid copyright issues.
